Just an update: After doing a factory reset and re-downloading everything i have not had any stuttering and ive been able to complete 4 or 5 missions with no issues. Could be that re-downloading MGS V might have had the same effect but that seems slightly less likeyl.
I just got a lenovo tab 2 a10-70 and have been liking it a decent amount. They have an 8 inch version of the tab 2 that is like $130. Both have great screens, SD card slots, run lollipop, and seem to have great battery life. I mostly use it for reading comics though so your milage may vary on gaming (seems to hold up well on everything but hearthstone).
